The inspiration for the launch of the Festival of Ideas was the widespread popularity of the annual Cambridge Science Festival, and the valuable communication experience that staff and students gain through engaging with the public. The Festival of Ideas focuses on fuelling the public’s interest in and involvement with the arts, humanities and social sciences in a unique and inspiring way. It aims to gauge the similarities and differences in the approaches to public engagement required for science, technology, engineering and maths, and for the arts, humanities and social sciences.
